"Javier Ajerman has known how to include in Sex Naturally!" all the components that make this work a practical, entertaining manual full of advice that will delight the reader, in the literal sense of the word. It has surprised me, I assure you, at the same time that it has made me smile in many chapters, because sex and laughter are, in the author's words "a sure path to shared happiness." Said Silvia Fominaya on the prologue.
